Update security/p5-Digest-SHA1 to 2.04.  Changes from version 2.02 include:

   Don't assume PerlIO_read() works like fread() even though
   it was documented like that for perl 5.6.  It returns negative
   on read failure.

   Implemented sha1_transform, required to implement NIST FIPS 186-2.

   Make it build on 64-bit platforms with 32-bit longs.

   Sync up with the Digest::MD5 implementation:
      - added clone method
      - addfile croaks if it can't read
      - the sha1*() functions warn if called as method
        or with reference arguments.
